Reproduction on the exact OS build: the bug can be proven present or absent. - -Safari Technology Preview is a separate build. Its version does not prove the version of system WebKit. +Modern source tags use `WebKit-7`. The 612 and early 613 trains use `Safari-`. ## Current certificate-info crash -The crash on macOS 27.0.1 maps as follows: +| Field | Value | +|---|---| +| macOS | `27.0.1 (26A434)` | +| Crash/Ravel UUID | `70BEE322-37EE-3B22-8012-4F76BA105C29` | +| `CFBundleVersion` | `22625.1.29.11.28` | +| `FULL_VERSION` | `625.1.29.11.28` | +| Candidate source tag | `WebKit-7625.1.29.11.28` — not public as of 2026-10-06 | +| Result | The shipped binary has the old one-argument `commitCertificateInfo` ABI; the fix is absent. | -```text -macOS: 27.0.1 (26A434) -Crash UUID: 70BEE322-37EE-3B22-8012-4F76BA105C29 -Ravel UUID: 70BEE322-37EE-3B22-8012-4F76BA105C29 -CFBundleVersion: 22625.1.29.11.28 -Prefix: 22 -FULL_VERSION: 625.1.29.11.28 -Candidate tag: WebKit-7625.1.29.11.28 -``` +The fix landed in `318982@main`. macOS 27.2 is a candidate for the first fixed system release, but public `WebKit-7625.2.*` source tags are not available yet. -The exact `.11.28` source tag is not public as of 2026-10-06; `.11.27` is public. The crash symbol and the `WebKit-7625.1.29` source family both show the old one-argument signature. Therefore the fix is absent from macOS 27.0.1. +## Data sources and maintenance -Ravel identifies macOS 27.2 beta binaries as `625.2.4.1`, `625.2.5.11.1`, and `625.2.7.1`. Public `WebKit-7625.2.*` tags are not available as of 2026-10-06. The fix landed in `318982@main` and Safari Technology Preview 251, so macOS 27.2 is a candidate for the first fixed system release, but source inclusion is not yet proven. - -## DuckDuckGo telemetry gap - -Current pixels do not include the exact system WebKit `CFBundleVersion`. The HTTP User-Agent cannot fill this gap because Apple returns the frozen `AppleWebKit/605.1.15` compatibility token. - -Add one field to relevant crash and WebKit failure telemetry: - -```text -webkit_build=22625.1.29.11.28 -``` - -Populate it from `Bundle(for: WKWebView.self).CFBundleVersion`. This makes OS-build-to-WebKit correlation deterministic on both macOS and iOS. - -## Sources - -- [WebKit source repository](https://github.com/WebKit/WebKit) -- [Current WebKit version configuration](https://github.com/WebKit/WebKit/blob/main/Configurations/Version.xcconfig) -- [Safari 15 / WebKit 612 version configuration](https://chromium.googlesource.com/external/github.com/WebKit/webkit/+/refs/tags/Safari-612.1.27/Source/WebKit/Configurations/Version.xcconfig) -- [Safari 16 / WebKit 614 version configuration](https://chromium.googlesource.com/external/github.com/WebKit/webkit/+/refs/tags/WebKit-7614.1.25/Source/WebKit/Configurations/Version.xcconfig) -- [Safari 17 / WebKit 616 version configuration](https://github.com/WebKit/WebKit/blob/WebKit-7616.1.27/Configurations/Version.xcconfig) -- [Safari 27 / WebKit 625 version configuration](https://github.com/WebKit/WebKit/blob/WebKit-7625.1.29/Configurations/Version.xcconfig) +- [AppleDB OS/build catalogue](https://api.appledb.dev/ios/main.json) +- [WebKit source and public tags](https://github.com/WebKit/WebKit) +- [WebKit `Version.xcconfig`](https://github.com/WebKit/WebKit/blob/main/Configurations/Version.xcconfig) +- [MDN Safari/WebKit release metadata](https://github.com/mdn/browser-compat-data/blob/main/browsers/safari.json) - [Ravel binary catalogue](https://ravel.dbg.re/browse) -- [MDN Safari release metadata](https://github.com/mdn/browser-compat-data/blob/main/browsers/safari.json) -- [Safari release notes](https://developer.apple.com/documentation/safari-release-notes) - [WebKit commit 318982@main](https://commits.webkit.org/318982@main) -- [Safari Technology Preview 251](https://webkit.org/blog/18194/release-notes-for-safari-technology-preview-251/) +- DuckDuckGo Apple browsers deployment targets: `macOS/Configuration/Common.xcconfig` and `iOS/DuckDuckGo-iOS.xcodeproj/project.pbxproj` -## Limits - -- One OS major contains multiple WebKit updates; use the exact OS build for conclusions. -- Ravel is in beta and does not index every historical Apple build. -- Intel and Apple Silicon binaries may have different UUIDs. -- An exact public tag may appear after Apple ships the binary. -- Verify released code, not only commit ancestry, because fixes can be cherry-picked. +To update this document, add new stable OS rows first.
